To all whom it may} concern."

Be it known that I, HARRY H. SC ROYER, a citizen of the United States, and a resident of the city of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Metal-Roof Structures and Seals for Car-Diaphragms; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being bad to the accompanying drawings, and to the numerals of reference marked thereon, which form a part of this specification.

This application constitutes a continuation of my co-pending application for "Metal car diaphragms, filed March 26, 1915, Serial No. 86,618.

This invention relates to an improved roof structure and seal therefor for use with metal type car diaphragms whereby adjusting and flexing movements of the diaphragm with respect to the car are permitted to take place, yet with the roof member affording a water tight shelter over the side walls of the diaphragm and with. sealing means mounted on the car co-acting with the roof member to provide sealing connection between thesame and the car.

It is also an object of this invention to construct a car diaphragm provided with a roof structure of improved design, and

equipped with sealing means to afford an efficient weather seal at the connection between the roof structure and the car itself.

It is also an object of this invention to construct an improved telescoping type of roof structure for metal -car diaphragms having an adjustable connection with the side walls of the diaphragm to permit warping or flexing movements of the diaphragm with respect to the car and between the parts of the diaphragm, and with sealing means associated with said roof structure to afford an efiicient seal at all points of connection thereof with the side walls of the diaphragm and the car itself.

It is furthermore an important object of this invention to construct a car diaphragm metal roof capable of longitudinal extension and contraction'with respect to the car the side walls of the diaphragm and with the car body itself.

It is finally an object of this invention to construct an improved type of roof structure for metal car diaphragms simple in operation and-construction and operating efficiently to afiord a weather proof passage through the vestibule diaphragm of a car.

The invention (in a preferred form) is illustrated in the drawings and hereinafter more fully described.-

In the drawings: 1

' As shown in the drawings:

The reference numeral 1, indicates as a whole a car body on which is secured by means of rivets, bracing or other suitable means an-angle end beam or plate 2, which arches over the vestibule opening at the end of the car. What may he termed the stationary member of the car vestibule diaphragm is adjustably connected upon beam uprightsB, forming a part of the end structure of the car and said stationary member comprises side walls 4 and 5 respectively of which the upper margin of each of the walls 4, is flanged inwardly as denoted by the reference numeral 6, and provided wlth a strlp of sealing material on =its upper surface. The rear marginal portion of each of the inner side wall plates 4, is flanged outwardly to receive the rear flanged margi n of the wall plates 5, brazed or otherwise rigidly secured thereto, and is bent into parallel relation with said plates 4 and 5, as denoted by the referencetnumeral 7 and. at its extreme margin headed over as denoted by the reference numeral 8. Secured upon the rear surface of the I-beam upright 3, is a resiiient retaining plate 9, one margin .of which is beaded over to interfit with the beaded portion 8, of the side wall member and a wear plate is mounted beneath the said retaining plate 9, against which the beaded portion 8, is confined. This connection of said side wall to the I-beam frame member 3, affords anadjustable connection for the stationary section of the diaphragm.

Inserted between the outer flanged margins of the respective side wall plates 4 and 5, are thin plates 11 and 12, on which sealing strips 13, are secured, as clearly shown in detail in Fig. 5. Rigidly mounted with the ends of the car is a vertical plate 14, and secured along the upper portion thereof andextending horizontally outwardly and gabled or apex-shaped is a stationary roof section or top member 14. The lower margin of said vertical plate 14, is flanged inwardly and rigidly secured thereto is a horizontal stationary ceiling plate 16. Also secured upon said vertical frame plate 14, and projecting outwardly horizontally therefrom is an apex compartment member 17 which together with the gabled roof or top member 15, afiords an angled compartment to receive the apex or gabled roof member of the movable section of the diaphragm therein hereinafter described.

movable section of the diaphragm is attached upon a face plate 18, and consists of side walls 19, the rear margins of which telescope between the sealing members 13, into the narrow compartment between the side walls 4 and 5, of the stationary section,

and the gabled or apex-shaped roof member 20, which is shown in plan view in Fig. 2, is of trapezoidal shape and adjustably con nected to said side walls 19. The means of attachment of said side walls 19, to the face plate 18, consists of a wear plate 21, secured upon the face plate with a resilient retain.- ing plate 22, secured thereover, and bent outwardly and headed inwardly to receive the beaded margin 24, of the side wall engaged adjustably therein. T he roof member 20, is flanged outwardly at its forward margin as clearly shownin Fig. 1, and rigidly secured to the upper portion on the rear surface of the face plate 18. The adjustable connection between the roof member 20, and the side walls 19, is shown in detail in Figs. 3 and 4, and for this purpose, the side margins of the roof member 20, are bent in-' wardly as denoted by the reference numeral 25, and'the top margin of the side walls 19,

are also flanged inwardly therebeneath with the extreme marginal portion bent in an acute angle to afford a limiting stop for the movement of the inwardly flanged portion 25, of the roof member 20. A strip of sealing material 28, is interposed between said taaaoaa respective inwardly flanged portions 25 and 25, to afford a seal therefor.

livotally secured to the rear surface of the face plate 18, beneath the gabled roof member 20', is a rearwardly horizontally ex tending rod29, which extends through the apex compartment 17, and slidably through the rear frame plate 14, and has coiled the diaphragm in all movements and in all positions of adjustment thereof. Pivotally mounted in inclined position on the front of the car end above the top wall member 11, are plates 31, angled with respect to one another and parallel to the gabled roof member 20. The lower ends of said plates are provided with a sealing strip 32, and springs 33, are associated with the hinged connection for said plates 31, to bear upon said plates and impel the sealing strip downwardly upon the respective inclined surfaces of said roof member 20, to seal therealong.

The operation is as follows:

The outer side wall sections 19, of the diaphragm are adapted to move inwardly telescoping with the respective side walls 4 and 5, which are adjustably mounted on the ends of the car so as to be capable of slight lateral movement. The roof member 20, moves beneath the stationary gabled roof member 15, within the end of the car, the

spring impelled sealing means 32, sliding over the surface thereof as said roof member moves inwardly therebeneath. Said roof member 20, is not only of gabled or apex shape, but converges rearwardly from the face plate 18, rearwardly to its rear margin as clearly shown in the plan view in Fig. 2, so that said roof member is capable of a.

transverse swinging movement rigid with the face plate 18, when such movements are imposed upon the face plate. Relative movements between the side walls 19, and said roof member 20, is permitted owing to the fact that a sliding sealing connection is provided therebetween, the top margins of. said side walls being flanged inwardly and the side margins of said roof member also being flanged inwardly and bearing downwardly thereon with the strip ofsealing material therebetween.

I am awarethat various details of construction may be varied through a wide range without departing from the principles of this invention, and I therefore do not purpose limitmg the patent granted otherwise than necessitated by the prior art.
